TILE.

SPECIFICATION forming part of Letters Patent No. 426,289, dated April 22, 1890.

Application filed October 14. 1889. Serial No. 326,986. (No model.)

To all whom, it may concern:

Be it known that I, ERNST CHARLESI'I LINDE? MANN, of the city of Baltimore and State of Maryland, have invented certain Improvements in Tiles, of which the following is a specification.

In the description of the said invention which follows reference is made to the accompanying drawings, forming a part hereof, and in which- Figure 1 is a plan view of three tiles formed in accordance with my invention and representing a portion of a roof. Fig. 2 is a section of Fig. 1, taken on the dotted line 00 Fig. 3 is a section of Fig. 1 takenon the dotted line 3 y. Fig. 4 is an under side view of one of the tiles.

Similar letters of reference indicate similar parts in all the figures.

In the said drawings, A represents the tile, the sides of which are parallel, as are also the top and bottom; but the top and bottom are not at a right angle with referen cc to the sides. Consequently the general form of the tile is that of a rhombus when seen from either the upper or lower side.

Looking at the upper surface of the tile, one lateral edge thereof has an upward projection a, which is hollow and tapers from the lower edge Z) toward the upper edge e. The other lateral edge of the tile has a bead cl, and at its upper edge a similar head 6, which extends around the projection a. (See Fig. 1.)

Such tiles as are intended to be used at the caves of the roof have the hollow projection a closed at the larger end or at the lower edge of the tile; but in all the tiles above the cave ones the hollow portion of the projection when seen from the under side represents a plain tapering channel. In making the channels tapering one tile will fit over another, as shown in Fig. l.

Each tile has its under side a channel or groove f, to receive the bead e of the underneath tile. This channel is shown in Fig. 4.

A portion of the side of the tile which overlaps the lower edge of the one next above it is cut away, as shown at g.

In tiling, the tiles are laid in a vertical row, beginning at the caves, and after one row is completed another is commenced, which overlaps the edge of the preceding one.

To admit of the tiles being laid in vertical rows, as before stated, it is necessary that the hollow projections a should be of tapering form, so that one tile may be placed over the next beneath it. As this hollow projection is at one lateral edge of the tile, it necessarily follows that when the tile is placed with the hollow projection in a vertical position the edge will be oblique to the vertical; and in order that the bead (1 may fit snugly against the inner surface of the tapered hollow projection a it also must be oblique. At the eaves, as the lower end of each succeeding tile overlaps the preceding one, in order to maintain a proper alignment, I make the lower edge at such angle as will admit of the lap and yet preserve a regular general outline of the whole series of tiles at the eaves. It will be seen, therefore, that the general vertical arrangement of the tiles and their oblique edges necessarily requires that the tiles be of rhomboidal form.

I claim as my invention A tile of the general form of a rhomboid, having the hollow tapered projection a, which has a portion of its lip at g cut away, as shown, the side bead (Z, upper head 6, which passes around the projection a, and the transverse channel f in its under side, substantially as and for the purpose specified.
